Description Incorrect invocation of NetworkBehaviour.OnStop<X> on Host.

If Nob is despawned via Destroy():

• All three OnStop callbacks execute, in incorrect order (OnStopServer->OnStopNetwork->OnStopClient)

If Nob is despawned via Despawn():

• OnStopServer is called. OnStopClient and OnStopNetwork aren't called until the next frame.
• If Destroyed before the next frame, OnStopClient and OnStopNetwork are not invoked.

Replication Steps to reproduce the behavior:

• Import attached package and start included scene
• Start server and client
• Click Spawn
• Notice two cubes in scene
• Click Despawn
• Notice cubes disappear, and the following logs show: [Nullrefs are caused by the Despawn-then-Destroy NetworkBehaviour not unregistering from TimeManager.OnTick]

Expected behavior Objects both despawn, invoking OnStopServer, OnStopClient, OnStopNetwork in order, and correctly unsubscribing from TimeManager.OnTick.
